CLAM support from the Catalan Government

This week it was finally made official: the Catalan Government (Generalitat) will be supporting CLAM through a special grant. The main goal of such grants is to support quality Free Software development in Catalonia. We hope to make good use of the grant and be able to bring CLAM to its 1.0 release. You can read the official announcement here.

Final release of CLAM 0.8.0

"Prototyper with streaming SMS transformations"

After two preview releases We are glad to announce the final 0.8.0 version of CLAM. This release has been thoroughly tested in GNU/Linux but not in Windows and OSX, which is a time consuming task to do with our current build system. The reason for thas is very simple: The current build system in Win and OSX is not completely automatic and requires some hand-tweeking. Instead of loosing time on that, we prefer concentrating effords in a new build system based on scons and library binaries, which promises being much more cross-platform frienly, among other goodies.

The next release (0.8.1) with the new build system will happen soon, because we have already been successfull in our first tests compiling CLAM library binaries and linking apps against it.

Now, going back to our current release, these are some of the important additons since 0.7.0

• Rapid application-prototyping. Build a CLAM application in two easy steps: Designing the processing network with the NetworkEditor and the application GUI using QtDesigner and the CLAM plugin featuring widgets for visualizing streaming data.
• Annotator. Another new CLAM application. It is a manual edition tool in which you can visualize and edit low-level and high-level descriptors of virtually any kind, segmentation marks.. The idea is to offer a tool for fine-tuning, visualizing, editing and testing description extraction algorithms.
• Enhanced CLAM Networks. NetworkEditor can run SMS transformations in streaming. Moreover the processing network can receive controls from Open Sound Control (OSC) messages and translate outcoming controls to OSC messages.
• QtPlots. Now features editable segmentation marks on all the plots, a break-point-function editor with auralization, a spectrogram plot and other goodies. See the doxygen doc to learn how to use it.
• XML enhancements including better error handling and reporting, an experimental backend based on libxml++ as an alternative to XercesC++ and partial document operations. Libxml++ is planned to be the official back-end on future releases but still some work is needed on error messages reporting.

For details in CLAM-specific new features, please refere to the ChangeLog

Compared to the last preview (pre2) release, these are the additions : (sumarized)
New libxml++ back-end, CLAM::Audio bugfixes and interface changes related to SetDuration and SetEndTime (keeping back compatibility), and lot and lots of small bugfixes and code cleanup.

CLAM release 0.7
Easier deployment, better plots and Processing Networks

We are glad to announce CLAM long-waited release 0.7. Main highlights in this release are:

• An easier deployment on GNU/Linux. After rewriting the configure.ac we are happy to say that now CLAM is easier to install on any distribution. If you are one of those that tried to install CLAM and you gave up because you didn't know how to handle the dependencies, please try this new relase. Among other things, you are now allowed to disable support for certain libraries at configure time.
• Progress in the CLAM Processings networks mode. We are almost there. Very soon you will be able to become a real clammer without writing a single line of code through the already usable Network Editor.
• Better Plots. Built using the QT framework and the qwt library we added new and more convenient plots with features such as: an audio plot with temporal markers, the possibility of quickly changing the color map to get a nice screenshot for your articles...
• Low-level descriptors have been thoroughly tested.

Looking forward for your feedback.

CLAM at ISMIR

The MTG is organizing the 2004 International Symposium on Music Information Retrieval (ISMIR, for short) (see ISMIR webpage). In this context on sunday september 10th there will be a tutorial on "Software Frameworks for Analysis of Audio and Music Signals" in which George Tzanetakis and Xavier Amatriain will give a general overview and will present both Marsyas and CLAM more in depth. More details here.

The new CLAM-devel web

We've created a new space (the clam/devel section) in our web with information about the general direction that CLAM development is taking (the roadmap), the more specific tasks, the proposals documents, and how all the ongoing progress is taking place.

We hope you'll find it quite interesting.

CLAM Release 0.6.1 "QT and VC7 support"

We are glad to announce a new CLAM release. This time, the main additions are two new features that have been very much asked during the last months:

• Support for integrating the QT toolkit in CLAM applications (all platforms):
  To achieve that, the build system (srcdeps) detects QT "mocable" headers and "uic" files and associate certain custom build steps to them.
• Visual C++ 7.1 support:
  Now, under the Windows platform, the build system generates both a .dsp file (VC6) and a .vcproj file (VC7). Fortunately the latest Microsoft C++ compiler is *much* more standard compliant.

In order to use CLAM projects with VC7 you'll only need to compile the new version of srcdeps and reinstall all the external libraries (go to the download page).

Please read the Build System chapter in the documentation for guidelines on these topics.

Of course, this new CLAM release contains a lot of minor bug fixes and enhancements. A better MIDI support among them. Refer to the ChangeLog for more details.

CLAM release 0.6.0

Major additions to this release are new audio file support: Now users are allowed to read and save ogg/vorbis, mpeg layer 1/2/3 (mp3...) and pcm based audio files. For example, you'll take advantadge of this new feature when opening files in the SMSTools example. As minor additions, we've fixed some bugs, enhanced code documentation, and enhanced LADSPA plugins support.

Please read ChangeLog for more details and contact us through the mailing list for any question.

Read the 'deployment' section of the manual for information about new externals libraries we depend on.
Note for VisualC++ users: new libraries zips are ready for download in the web. The zip for 'fltk' has also changed.

CLAM release 0.5 is presented!

• Instead of CVS access, CLAM and related external libraries are now offered as tarballs. Visit our download area.
• New build system to make it easier to compile any CLAM project both in GNU/Linux and MSWindows.

• Major debugging and testing of the whole framework.
• New visualization module.
• Almost ready non-supervised mode, see Network Editor example.
• Please read ChangeLog for more detailed information.
